`isoband` 包安装失败，`testthat.h` 未找到

Question

我在Ubuntu 18.04.4 LTS 上安装了R (version 3.6.3 (2020-02-29), Holding the Windsock)。当我尝试从源代码安装ggplot2 时，依赖包isoband 的安装失败，找不到testthat.h。完整输出：

我已经尝试过手动安装testthat，但似乎不适用于R 3.6.3：

...

 .onLoad failed in loadNamespace() for 'pkgload', details:

  error: package ‘testthat’ was installed by an R version with different internals;

任何想法都将不胜感激。

解决了。问题的原因是经过一系列Ubuntu 和R 升级后，我的系统上仍然存在一些从源代码安装的过时软件包。

首先我打开了一个R 控制台并寻找使用3.6 之前的版本构建的R 包的路径：

> unique(subset(as.data.frame(installed.packages()),
                grepl("^3\\.[^6]", Built))[, "LibPath"])
[1] /usr/local/lib/R/site-library /usr/lib/R/library 

由于无法在这些过时的包上应用remove.packages()，我切换到bash，并列出了所有包路径：

>grep 'Built: R 3.[0-5]' /usr/local/lib/R/site-library/*/DESCRIPTION /usr/lib/R/library/*/
DESCRIPTION

我已删除（仅从/usr/local/lib/R/site-library/ 和/usr/lib/R/library/ 中删除）先前命令输出中的包，现在一切正常。
